An expedition sent to the primitive aboriginal outback of Australia hears rumors of a lost white woman.
They do make it to Australia and then eventually to a very remote area.
There they do find a white women who was shipwrecked way back and is married to a tribal Aborigine and is mother to his blond child.
She does not want to go back with them.
That is the thread of the story.
The title may misleading.
This is not action or drama packed and there is no blond captive.
It`s more or less an old film that exploit the interest in primitive peoples and human evolution for entertainment value.
Where it differs from others is that it makes a clear effort to appear scientific and includes Harvard professors and actual famous names in science.
